If March 21st the first day of spring then why was it still snowing in March 21st 2018. Clearly this means spring does not begin in March.?

answers:
say: Sometimes there is snow even in April so even in April the spring doesn't begin yet if you think about this in the way you just did.

Snezzy say: You need to learn about 1816, the "Year Without A Summer." It's also called Eighteen Hundred And Froze To Death. Crops failed because of the cold weather and many starved. See the Source listed below. Fascinating.

Grundoon say: Is your knowledge of science, "Instinctive?"

say: There is no rule that it can't snow in spring, or be 80° and sunny in Winter. The seasons aren't based on the weather, they're based on the number of hours of daylight and since the vernal (spring) equinox occurs in March, the day that the hours of daylight and dark are equal, that was chosen as the starting point for Spring. Summer begins on the day of the highest # of daylight hours, Autumn beings when daylight/dark hours are equal again, and Winter beings on the date of the fewest number of daylight hours.

Lesson over.
